International Classification:

H03F 3/26

US Classification:

330267, 330263

Abstract:

A unity gain buffer is provided. The unity gain buffer includes two complementary pairs of emitter followers and two bias current sources. The top bias current source is arranged to provide a bias current so that, if the input voltage is greater than zero, the bias current provided by the top current source increases at the input voltage increases. The bottom current source is arranged to provide a bias current so that, if the input voltage is less than zero, the bias current provided by the bottom current source decreases as the input voltage decreases.

International Classification:

G09G005/00

US Classification:

345/211000

Abstract:

A graphics processing system, methodology, and signal structure are disclosed wherein commands are transmitted from a graphics controller system to a graphics display system along with frame data and synchronization information. The commands instruct the graphics display system to perform certain operations, such as performing video processing on the frame data, controlling parameters of the display, performing power management operation, and well as send information back to the graphics controller system. The signal structure entails transmitting the command signal from the graphics controller system to the graphics display system during the vertical synchronization width and/or horizontal synchronization width respectively of the vertical and horizontal synchronization signals and when a data enable signal is asserted.

Assignee:

Ciba Corning Diagnostics Corp. - Medfield MA

International Classification:

G01N 114
G01N 3510

US Classification:

7386434

Abstract:

An obstruction detection circuit for detecting an obstruction of a sample probe of an automated sample aspiration/dispensation device and a method for detecting such an obstruction. In one embodiment the obstruction detection circuit includes a pressure sensor measuring the pressure in a fluid conduit connecting a pump and the sample probe orifice. The pressure within the connecting fluid conduit is measured by the pressure sensor shortly after the start of the aspiration or dispensation of a fluid volume by the automated sample aspiration/dispensation device. The pressure within the connecting fluid conduit is again measured after the completion of the aspiration or dispensation, and if the pressure has not returned to a predetermined range within a predetermined amount of time, an error condition is reported.

International Classification:

B65B 304

US Classification:

141 94

Abstract:

A liquid supply module includes one or more sets of bulk liquid containers each supplying a respective reservoir via a liquid supply line. The bulk liquid containers and reservoirs are vented above the highest liquid level in the system. A pump periodically removes a known volume of liquid from a reservoir which is replenished from a bulk liquid container. A sensor detects a liquid/air transition in the liquid supply line to the reservoir indicative of the exhaustion of liquid resupply from the bulk liquid container. Art air vent solenoid valve in communication with the reservoir is closed when an empty bulk liquid container is replaced. Normal pump operation siphons liquid out of the bulk container after container replacement. A control system tracks pump iterations and calculates a number of executable iterations remaining before the reservoir runs dry. With a fresh bulk container in place, the air vent solenoid opens the reservoir air vent upon detection of an air/liquid transition allowing liquid to flow by gravity from the bulk container into the reservoir.
